Filed: 1994-03-29
Abstract: PURPOSE:To enhance durability by defining the material of a cemented carbide tip for both ends of cutter bits as low hardness and high toughness out of cemented carbide tips installed in parallel to cutter bits and the material of a cemented carbide tip in the central part as high hardness and high toughness. CONSTITUTION:A tip mounting recessed part 14 is formed on the tip of a sheet- like base metal 13 which constitutes a mounting part of the base end. A plurality of cemented carbide tips 15, 16, 17 and 18 are fixed with the tip mounting recessed part 14 by brazing 16 in such a state that they may line up breadthwise. To braze with the tips 15 ad 18 on both ends, there is adopted a material having a low hardness and high toughness out of the cemented carbide tips 15, 16, 17 and 18. Then, when excavating a hard ground or the like by mounting a cutter bit 11 to a cutter head of a shield driving machine, a face pressure exerting on the chips 15 and 18 on both ends is reduced, thereby protecting the chips 15 and 18 from being damaged. Although the tips 15 and 18 are subjected to wear out during excavation work, the properties of the hardness and high toughness tips 16 and 17 prevents a drop in their wearing properties.

Inventor: SAKAI HIDENORI
IPC: C08L7/00
Filed: 1982-04-12
Abstract: PURPOSE:A polyethylene composition excellent in moldability and suitable for high-strength monofilament of good surface appearance, prepared by adding calcium laurate to polyethylene having a specified density, a specified melt index and a specified MW. CONSTITUTION:0.05-2.0pts.wt. calcium laurate is added to 100pts.wt. polyethylene with a density of 0.910-0.975, melt index <=2g/10min and weight-average MW/number-average MW<=5. When the above melt index is above 2g/10min, the strength of monofilament is insufficient, and when the MW ratio exceeds 5, no sufficient strength of monofilament can be obtained, and besides high-draw ratio monofilament can not be obtained because the spinnability is lowered. When the amount of calcium laurate added is below 0.05pts.wt., its effect is small, whereas when the amount is above 2.0pts.wt., the essential properties of polyethylene are lowered and besides slip at the screw part of an extruder increase to lower the moldability.

Abstract: PURPOSE: To prevent the slant cutting of the paper by a paper holding means for blocking the movement of the paper in the pulling direction during the cutting.  
     CONSTITUTION: The paper is pulled toward the cutter 14 to cut so that the base of the paper is brought into contact with the cutter edge 14 1  as coming from the outlet 9. And the contact press force of the paper causes the lever 13 to turn clockwise around the shaft 12 against the tension spring 18, and the projection 15 turns toward the projection receiving member 16 so as to push the paper between the members 61. The pressing force is strengthened enough to pull the paper strongly with an aid of the leverage of the lever. Therefore, the paper pressing action prevents the of the paper from being drawn out by the tension force during the cutting thereby making the paper easier to cut while preventing the slant cutting completely.
